USA NS Bolt-On


Available In 4-string, 5-string, and 6-string


The NS Bolt-On combines legendary design with bolt-on construction to yield an extremely versatile and lively bass. Although Spector is well-known for neck-thru construction, the NS Bolt-On series has been adored by players over the decades for its unique tonal properties, effortless playability, and lighter weight. The bodies of these instruments are individually crafted to order, allowing the player to choose their favorite combinations. Our options for tone woods include Mahogany, Ash, Alder, and Reclaimed Redwood. Each of these species has its own unique tonal properties that are well-suited for a variety of styles. Our Bolt-On basses also feature premium top woods to lend each instrument its own unique identity. Available options include premium 5A Quilted & Flamed Maple, unique varieties of Spalted maple, Buckeye Burl, Walnut Burl, and other exotic species. Each neck is carved from 3-piece North American Maple and can be paired with Pau Ferro, Birdseye Maple, or Ebony fingerboards. We proudly stock pickups and electronics from EMG, Aguilar & Darkglass, but will gladly accommodate requests from other reputable suppliers. All hardware is professional grade including Hipshot bridges, Gotoh tuners, and Dunlop Strap Locks. Players can choose from a wide variety of stains and finishes, as well as the ability to customize their own color.
